PRESS BUTTON.

Application filed May 31, 1928, Serial No. 588L855, and in Germany November 24, 1927.

This invention relates to a press-button socket-men'iber, the hood of which terminates in a socalled riveting neck. In these button parts it happens when riveting them to the 'labric for instance by means of fixing washers, caps or the like, that the pressure of riveting compresses or deforn'is the slots in which the spring branches are guided, in such a n'ianner that after the riveting stamp or punch is withdrawn, the branches can no longer snap into the slots, owing to which the socket-member becomes useless. This drawback is avoided by stiffening the hood of the socket-member by means of longitudinal ribs.

A cons ruction according to the invention is illustra ed in the accompanying drawings.

In the said drawings: v

Figure l is a longitudinal section,

Figure 2 is a cross-section and Figure 3 a plan of the improved socketmember.

The socket-men'iber is constituted in the well-known manner by a cup with the spring 4t which engages in slots 3 of the hood 1. In the latter, ribs are provided on the leftand on the right of the slots 3 on both sides throughout the wholelength of the hood 1, owing to which the hood is stifi ened. This stii'l'ening of the hood takes up the riveting pressure and does not permit narrowing of the slots.

In order still further to weaken the influence of the riveting pressure on the deformation of the slots, or in order to facilitate the springing required for the riveting and after the turning outward of the riveting neck 2, at the edge of the riveting neck are provided weakened points 6 which however are not such as to permit a bursting of the riveting edge neck during the penetration of the riveting neck through the fabric, that is to say during self-holing.

I claim 1. A press-button socket of the character described including a hood provided with spring engaging slots, and longitudinal stiffening ribs formed in the said hood close to the ends of the said slots for preventing compression of the slots.

2. A press button socket including a hood having opposed horizontal slots therein, a cup continuing from one end of the hood and surrounding the slotted portion thereof, a spring in the cup and having portions passing through the slots, a riveting neck continuing from the other end of the hood, and longitudinal ribs formed in the hood close to the ends of the slots to stiffen the hood and to prevent compression of the slots.

In testimony whereof I affix my signature.
